FRUIT-EVAPORATOR.

SPECIFICATION forming part of Letters Patent No. 367,514. dated August 2. 1857- Application filed January 6, 1857. Serial No. 223,535. (No model.)

pertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specifica tion.

Figure l of the drawings is a representation of a vertical longitudinal section on lineg/ y of Fig. 2. Fig. 2 is a transverse vertical section on the linerv a?, Fig. l. Fig. 3 is an enlarged vertical section in detail through the tubes F Fand their steam-chambers. Fig. 4 is a detail view showing the construction of the StandeV ards L. Fig. 5 is a section taken horizontally through the evaporator in the plane indicated by dotted line :c x on Fig. 1. Fig 6 is a perspective of the angular standards E.

My invention relatos to improvements in fruit driers or evaporators of the class in which steam is used to vdry the fruit when cut or sliced and laid on stages or platforms; and it consists in the construction and novel arrangement of parts,- hereinafter described, illustrated in the drawings, and pointed outin the claims hereto appended. Y

Referring to the accompanying drawings, A represents j a rectangular boiler resting on proper supports belowits corners or at other proper points.

a is a flange, about one inch high, surround ing the upper surface of the boiler, for the purpose ofretaining the sliced fruit thereon.

At one end ofthe boiler is a shallow steamchest, B, which runs transversely across the former and is preferably about as high as the flange.

Through the roof of the boiler, within the steam-chest,are the apertures b, through which the steam escapes from the boiler into the The apertures are near the cor'- ners of the steam-chest, and above the apertures atleach corner a tubular projection or nipple, c, rises from the roof of the boiler, and

is threaded, as shown, to engage the expanded and threaded lower end of a vertical pipe, O, hereinafter more fully referred to. The boiler is supplied through the inclined tube or pipe c', passing under the steamchest and having its outwardly and upwardly inclined end closed by a screw-cap, as shown.

D is a rectangular steam-chamber above the boiler, from the floor of which, near the corners of one end,'depend the tubular projections or nipples d d, which are threaded to engage the expanded and threaded upper ends of pipes d, which enter in the upper ends of the pipes G, the latter surrounding and support-ing the former, and both sets of pipes supporting or aiding to support one end of the chamber D upon thc boiler. The said chamber is surrounded at its upper surface by a ilange similar to the flange a, and serving a similar purpose. The end of the chamber D, opposite the steam tubes or pipes G and d', is supported upon the boiler by standards E, which are bent at right angles and have their edges rolled outward, so as to inclose and hold the rods e thus secured to the edges. The upward projections of these rods enter vertical sockets e', secured to the edges of the chamber D, on each side of a corner of the same, while their downward projections enter similar sockets, e', similarly situated on the edges of the boiler. j fis a tubular projection or nipple depend ing from the floor of the chamber D, midway between the projections d d, and threaded to engage the expanded threaded end of a tube, F, much smaller in diameter than the pipes d.

The tube F enters a tube, F', of somewhat larger diumeter,havin g surroundi n git at a suitable point a downwardly-opening thimble or sleeve, f threaded to engage over a threaded tubular projection or nipple, G, which stands from the roof of the stean1chest B, midway between the projections ,p c. The tube F eX.- tends downward through the projection or ,nipple G and passes through openings in the roof and door of the steanrchest, and has its lower end, which rests upon the door of the boiler, either provided with lateral openings flf" or cut away at one side to allow the water flow down into the boiler.

IEO

of condensation from the steam-chamber D to The steam-chamber D is provided on its upper surface with a steanrchest, I-I, in all respects similar to the steam-chest B, but at the opposite end of the'device; and it has upon its upper surface opening into it above apertures 7L h in its floor the threaded nipple c.

I is a steam-chamber similar tothe chamber D, except that it is unprovided with a steamchest on its upper surface, and d is a threaded nipple. C and d are steam-pipes. K K are tubes for the descent of water of condensation from the chamber I to the chamber D, which tubes are arranged and connected similar to the tubes F F, respectively, in Figs. 2 and 3.

L L are standards supporting the chamber I on the chamber D as the latter is supported on the boiler by the standards L. lI he standards, steam-pipes, and tubes are made of such length that the chamber I) inclines slightly downward toward the steanrpipes connecting it with the boiler, and the chamber I inclines downward toward the pipesV connecting it with the chamber D, so that the water of eendensation -ean run easily down to the boiler.

The chamber I is provided at its higher end upon its roof with a threaded nipple, M, having a screw-nozzle, on, to discharge the vapor formed. Thesteam rising from the boiler into the steamchest passes up through the described steampipes into the steam chamber D and thence into the steam-chest I'I, whence it passes by the described steam-pipes into the chamber I, and the vapor passes out through the nozzlem. The water of condensation passes in the reverse direction through the described tubes tothe boiler. To prevent the said water fromdeseending through thesteam-pipes, partial partitions X are provided, which rise from the floors of the Chambers D and I nearly to the tops thereof, and run from side to end and so cut the descending water ofi' from the entrances ofthe steam-pipes, while the steam can rise over said partitions.

It is evident that a greater number of steamchambers can be used, if desired, as they are but reduplications of each other, the highest only dispensing with a steam-chest.

The rise of the steam-chests causes the steam rising to the chambers-to be more dry, so that evaporation is made more rapid.

Having described this invention, what I claim, and desire so secure by Letters Patent,

l. In a fruit-drier, the combination, with the boiler, steam-pipes, the steamehambers, and the partial partitions rising from the tloors of said chambers, so as to prevent the water of condensation from flowing into the steampipes, of the tubes for the descent of the water of condensation, having their ends enlarged and threaded, and the threaded nipples for the engagement of said ends, substantially as specified.

2. The combination, with the boiler, steanr chambers, steam-chest, steam-pi pes, and tubes for descent of water of condensation, of the standards L and E, the rods e, and sockets e', substantially as specified.

In testimeny whereo't1 I afIiX my signatnren presence of two witnesses.

NATIIANIEL GLYNN.
